Add Reanimator format export support

Implement export to Reanimator format for asset tracking integration.

Features:
- New API endpoint: GET /api/export/reanimator
- Web UI button "Экспорт Reanimator" in Configuration tab
- Auto-detect CPU manufacturer (Intel/AMD/ARM/Ampere)
- Generate PCIe serial numbers if missing
- Merge GPUs and NetworkAdapters into pcie_devices
- Filter components without serial numbers
- RFC3339 timestamp format
- Full compliance with Reanimator specification

Changes:
- Add reanimator_models.go: data models for Reanimator format
- Add reanimator_converter.go: conversion functions
- Add reanimator_converter_test.go: unit tests
- Add reanimator_integration_test.go: integration tests
- Update handlers.go: add handleExportReanimator
- Update server.go: register /api/export/reanimator route
- Update index.html: add export button
- Update CLAUDE.md: document export behavior
- Add REANIMATOR_EXPORT.md: implementation summary

Tests: All tests passing (15+ new tests)
Format spec: example/docs/INTEGRATION_GUIDE.md
